ABSTRACT
To be offered a festschrift is a great honour; to have such editors and contributors makes the honour greater still; and to be given the last word makes the offer irresistible. The only drawback is that, as saying how much I agree with everyone would take too long, and be less useful to readers, than saying where and why we disagree, my replies may seem ungraciously combative. Still, since we all know how debate can advance philosophy, I hope no one will infer any disrespect from my disagreements. On the contrary, it is to the work and friendship of these colleagues, mentors and students that I owe much of the understanding and pleasure that philosophy has brought me. For that I am very grateful to them all.
